3.1. Prove that a cyclic code $\mathcalC$ has a generator polynomial $g(x)$.

The codewords are $(0, 0, 0)$ and $(1, 1, 1)$. The Hamming distance between them is 3.
is equal to the minimum weight of any non-zero codeword. It is also equal to the minimum number of linearly dependent columns in the parity-check matrix 2. Proving Bounds is equal to the minimum weight of any non-zero codeword

When finding the minimum distance of a code, look for the minimum weight of non-zero codewords if the code is linear. 2. Linear Codes Working with Linear Codes
Ideal for the algebraic and theoretical proofs in the book.
. Step-by-step solutions help students identify where arithmetic or conceptual errors occurred in their manual calculations. Understanding Decoding Algorithms
The text places heavy emphasis on bounds. If a problem asks you to prove whether a code with specific parameters exists, you must test it against the major bounds:
To help you get through your assignments without relying entirely on a solution manual, let’s break down two of the most common types of problems found in the chapters of San Ling's text. 1. Working with Linear Codes
